First, the reason for nut fastener slip wire

Metal fatigue: After repeated use of the nut, the sharpness of the thread will be reduced, and the area of engagement on the thread will be smaller, resulting in the nut easy to slip when fastened.

The nut housing is too hard: the nut housing itself is too hard and not strong enough, so whether it is loose, fastened or used for a long time, it will cause the nut to slip.

Poor processing quality: there may be a large processing error during nut production and processing, resulting in a large internal stress inside the nut, which leads to easy wire slip during use.

The surface of the bolt thread is not smooth: if the surface of the bolt is not smooth, it will cause the nut to be difficult to twist on the thread when it is tightened, resulting in the nut slipping wire.

Incomplete cleaning: the nut needs to be cleaned before use. If there are grease, dust and other stains on the surface of the nut, it will cause the nut to slip.

Over-tightening: If the nut is too tight, it will not rotate when it falls on the bolt, resulting in the nut slipping.

Second, the processing method of nut fastener slide wire

Replace the nut

If the degree of nut slip is serious, it is generally recommended to replace a new nut to avoid affecting the normal operation of the device.

Tighten the nut

If the degree of the nut slip is light, you can try to increase the nut strength, so that the screw thread of the nut and bolt can be smoothed to a certain extent, so as to solve the problem of the slip wire.

Use electric wrench

The electric wrench has the feature of high speed rotation, which can quickly tighten the nut. During use, it is necessary to choose the appropriate torque size to avoid damaging the nut.

Force finding

If the reason for the nut sliding wire is uneven fastening force, the problem can be solved by changing the position of the force point. The point of force needs to be moved outward, which makes it easier for the nut to rotate.

Surface treatment

The selection of bolts and nuts with smooth surfaces can effectively reduce the probability of wire slip. In addition, the treatment of screws with rough surfaces, such as deburring, polishing, etc., can also make the surface of the screw smoother and reduce the probability of slipping.

Increase and decrease pressure

When in use, the pressure can be increased or decreased according to the degree of nut slide. If the nut slide is light, the pressure can be appropriately increased, which can make the nut easier to rotate. If the nut slide is serious, the pressure needs to be reduced appropriately.

Treated bolt surface

If the reason for the nut fastener slip is that the bolt surface is rough, smooth processing methods can be used, such as polishing, etc., to make the surface smoother and reduce the probability of nut slip.

Clean nut face

Before using the nut, it is necessary to clean it to remove stains such as grease and dust on its surface and prevent stains from causing the nut to slip.

The above is the reason and treatment method of the nut fastener slide wire, and the appropriate treatment method needs to be selected according to the specific situation. When in use, pay attention to maintenance and maintenance to avoid affecting the normal operation of the equipment due to the nut slide.
